Abstract: 
Measurements of the linear polarization of resonantly scattered photons have been used for model independent parity assignments in nuclear resonance fluorescence experiments. The novel result of the present study was the first observation of enhanced electric dipole excitations in the deformed nuclei 150Nd and Dy-162 at excitation energies of 2.414 and 2.520 MeV, respectively. The transition energies and the enhanced B(E1) up strengths of 3 and 5 x 10(-3) e2fm2 support the interpretation in terms of the predicted new type of collective electric dipole excitations in deformed nuclei due to reflection asymmetric shapes like octupole deformations and/or cluster configurations.
